6 Claims. (01. 22937) My invention relates to the art of paper contab of the paper which would otherwise serve no tainers suitable for the transportation, storpurpose. age, or vending of granular or liquid products. Still another advantage of my present design Because, however, of its special adaptability for is in having trapezoidal sides that present a subliquids, I prefer to term my invention a paper stantlal amount of space that can be used for 5 milk bottle. the advertising of various products, to the end The general public has already accepted as that the net cost of the bottle, to a dairy, can be desirable the single service paper milk bottle. It substantially reduced and be made much less than has many practical characteristics; the principal the net cost of each use of glass bottles.

hanging it as on a doorknob. Referring to-the drawings, throughout which Another advantage of my, present construclike referencecharacters indicate like parts, nu-

tion is that it admits for certain uses, as in the meral l6 generally designates the blank from transportation of the provision of a cream which my bottle is formed. This blank is dieline window so that the one objection the housecut from a single piece of paper, with all the wife may have to a paper bottle in contradistincparts going into the construction of the finished tion to the glass,is satisfactorily overcome. This bottle joined together along, at least, one full window is formed with reinforcing, which again side, so that there are no small parts that may is made without wastage, by merely utilizing a be lost or torn oif. Each of the four sides is formed as a truncated triangle so that when the bottle is formed it has theshape of a frustum of a pyramid. The proportions should be made to suit the commodities used. It is desired to point out that my container may be used for any granular product, for cereals, or for various liquids other than milk, such as fruit, or vegetable, juice, syrup, honey, catsup and many other such products.

In the present arrangement however I have found it desirable to retain in general the principal dimensions of the. standard milk bottle as the trade is already equipped with many handling and filling devices, and transportation cases, normally provided with square partitions,

so that if the general proportions of a two inch square top, a four inch square bottom anda nine inch height are maintained my present bottle can be used in much of the equipment that is now used for quart milk bottles. In the same way a suitable reduction in size would make it convenient for use in the handling equipment of the smaller size milk and cream bottles.

The four sides as l8, I9, 20, and 21 are scored as at Ila, I9a, 20a, and -2la, so that they will naturally fold on these folding lines. One side as I! is provided with an extension on one of its sides to provide the sealing fiap 22 which is used to seal the body of the bottle after the showing in Figure 2 in which fiap 22 is normally disposed inside the bottle with side 2| overlapping the same, the two being joined together with a suitable adhesive.

Each of the sides has an extension bottom member attached to its lower end as 24, 25, 25, and 21. These are separated by the cut occurring at 24a, 25a, 26a; between the sides and g the bottom portions are narrow, bead-forming portions as 29, 30, II, and 32. Each of these bead portions is provided with the scored foldi9 and 2| by the scored foldinglines 54. Tabs and 52 provide the carrying or supporting handle for the bottle.

In tab 5| and side iii, are struck-out mating openings as 55 and 51 which are disposed equidistant from folding line 54.

Tab 53 is arranged to form the top closure of the bottle. It consists of the top closure member proper 50 which is pierced for'the rectangular filling and discharge openingv GI and has side sealing tabs 62 and 53 each of which is provided with a scored folding line which separates it from the top member 50 proper. Midway in tab 5toccur three scored, folding lines 55, 55, and 61. The remainder of tab 53 is the top reinforcing portion 10. This member is provided of a size substantially equal to member 50 proper and arranged with an embossed or press-formed indentation 12 of sucha size as to wedge firmly into opening 5! so as to provide a sealing closure therefor. For certain purposes it has'been found desirable to provide that tab 58 be provided with a further extension. This is illustrated in detail in Figure 13 wherein a tab extension, shown in dashed line'at 15, is provided which will fold back into depresaion 12 and reinforce the same as shown in Figure 9 andFigure 13, forming the reinforcement member 15.

Forming the bottle and is secured, with opening 55 in registry with Jo'pening 51, to side I! by a suitable adhesive and thus provides a secure frame for the transparent material forming the inspection or creamline window.

-The next operation is to fold the paper blank along the lines Ha, I 8a, 25a, and Us, and tab 22 is secured by a suitable adhesive to side 2|, after the showing of Figure 2. The bottom is preferably formed next.- This is accomplished by folding tab 24 upwardly into the base of the bottle, folding the same along the scored lines 35 and 35 so that bead portion 25 is against side I! after the showing of Figure 3. Tab 25 is placed in a horizontal position and edge sealing members 40 and 4| then assume the position shown in Figure 3, where they and member 25 are suitably secured to the side members preferably by a waterproof adhesive. In a. like manner the other tab members, 25, 25, and 21 are secured in place after the showing of Figures 4, 5, and 6. When finished, as in Figure 6, it will be observed that a very strong bead is pro'- vided with a bottom of laminated structure giving four thicknesses of material. This provides a stiff, form-retaining wall, across the large end of the bottle and {serves as a base or bottom.

.The top closure is made after the showing of Figures 7, 8, 9, 10, and Figure 11. Figure 7 shows the end members in the position it will assume when the sides are glued together and the bottom in place.

In Figure 9 pad 53 has been bent along folding line 54 and brought across the top of the bottle. It is then folded on line 61 and back again on itself on line 58. This gives a bearing portion which can be secured to side i9 by a suitable adhesive. The tab is again folded along 55 so as to leave the closuremember disposed somewhat above the filling, or pouring opening ii. The bottle is nowin position for filling and after filling has been accomplished indentation 12 is seated within opening 5| after the showing of Figure 10.

As soon as the bottle has been filled tabs 55 and 52 are overlapped after the showing of Figures 14 and l6 and joined by some suitable adhesive or by stapling at .52. The bottle or container of course maybe made of any suitable material. At present the material which seems most practical is an impregnated paper so calendered or finished that it will form a good base for parafiin treatment of the inside of the bottle. If the bottle is to be used for liquids the inside should be paraflined and preferably just before the bottle is filled so that the sterilizing qualities of the paraflin can be utilized to the fullest and any bacteria or the like which may have accumulated on the surface of the paper will be covered by this paraffin coating which in addition to performing the flmctions of waterproofing and sterilizing the bottle also acts as a sealing agent to fully seal all the folded seams wherein leaks might'otherwise result.

It will be apparent, it is believed, that tabs and 52 when they are cemented or stapled together form a very convenient carrying handle and also provide a bail which can be used for suspending the container from a doorknob, hook, or the like, and thus keep the package away from many sources of contamination, especially from animals.

The foregoing description and the accompanying drawings are believed to clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illus trative and that such changes in the invention may be made as are fairly within the scope and spirit of the following claims:

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
